electric fan

[z_boi]

Im planning on purchasing an electric fan from kragan so i need to know what to get to install it and where to get it.?

You sould be able to buy everything needed to install the fan at the store that sells it to you. Usually the fan comes with all that is needed to install, or a "install kit" is sold separately. You may want to get a "Thermostatic control kit" to control the operation of the fan, unless you want to switch it on and off manually.

i should be able to get the thermostatic control at the same place also?

Most stores that would sell the fans would also stock the controls, or at least be able to order the kit from the same manufacturer.

Kragen should be able to do this, but who knows. They are not my favortie source for anything other than oil that is on sale. I routinely got lousy service from them so I spend very little money in any Kragen store.

I just got one at the junkyard from a 93 V6 3.8 Ford Tarus. It's two speed and has a shroud that fits the radiator close to perfect.It pulls way more air than even the Flexlite fan I have on on truck.It was $20.I just need to buy a temp control.I recomend not getting the flexalite contoller with cap. tube.(kind of flimsy).

Before you go too far, you should check the clearance between the front of the engine and the radiator. I recently spent some time at both Checker (same as Kragen) and Autozone looking at their fans. Even the 14" models were 3" thick, and all suggested 2" of clearance. I have at the most a little less than 4" between the bolts on the water pump and the radiator so it would be rather close. And moving the fan to the side would mean taking off the fan shroud which would reduce cooling.

Some say you can mount the fan in front of the radiator, but everything I've read says this is not as effective as putting it behind in a "puller" configuration.

FWIW, I don't believe my 73 has been in any accidents.

So far the only thing I'm concerned with is Starting amps on my Tarus fan .I haven't measured it yet myself,but was told it pulls 130 amps on start up and 40 amps running amps in high speed mode. I have an upgraded alternator with a 90 Amp out put.Maybe I'll just run it in low speed .This is another thing to keep in mind ,can your alternator handle the load?Don't forget you might be running your lights ,stereo also.The clearence is perfect ,I have about an inch to spare.

The Starter motor doesn't even pull that! Most fan relays are rated around 30 Amps. What ever you pulled the fan outa's original relay rating will be more than the maximum that the motor will pull at any given time, and max duty cycle. :devious:

I believe a starter pulls from 150-250 amps.That's why batteries are rated in cranking amps,usually 500 - 650 cold cranking amps?The battery puts out this current not your alternator.What I was concerned with is the instantaneus current rating on the relays I have. I know they are rated for 30-40 full load amps ,but wasn't sure what instantaneus amp rating the contacts had . Rather than taking a chance of melting the conatacts I was just going to use the low speed windings of the two speed motor until I got a cut sheet on the relays I'm using.

Oh, I do not have the original relay that the fan came with.But yeah that one would be rated for that fan.
